Product Overview: 24C04WQ EEPROM by STMicroelectronics

The 24C04WQ is a high-performance 4-Kbit serial I²C bus EEPROM (Electrically Erasable Programmable Read-Only Memory) produced by STMicroelectronics, a global semiconductor leader known for its innovative and reliable products. This EEPROM is part of ST's extensive EEPROM product line that offers the ideal solution for flexible and robust data storage in a wide array of electronic devices and systems.

Designed with dependability in mind, the 24C04WQ features a memory density of 4 Kbits, organized as 512 x 8 bits, which is optimal for storing configurations, settings, and small data logs. It operates over a wide voltage range from 2.5V to 5.5V, making it versatile for use in various power environments and suitable for battery-operated applications.

The device supports a bidirectional, two-wire serial interface, which ensures compatibility with the I²C protocol, allowing for easy integration into existing systems with minimal additional components. The bus speeds can go up to 400 kHz, enabling fast data transfer rates that are essential for performance-critical applications.

One of the key features of the 24C04WQ is its write control mechanism, which includes both byte and page write modes. The page write mode allows for up to 16 bytes of data to be written in a single write cycle, significantly improving the efficiency of data logging operations. Additionally, the EEPROM has a self-timed write cycle with automatic erase-before-write capability, simplifying the write operation and ensuring data integrity.

For security and data protection, the 24C04WQ comes with a hardware write protect pin. When activated, this feature prevents accidental data overwrites and ensures the safety of stored data during critical operations or after deployment in the field.

STMicroelectronics has designed the 24C04WQ with a 100,000 write/erase cycles endurance and a data retention period of 40 years, guaranteeing long-term reliability for applications that require frequent data updates. The device is available in various packages, including the ultra-compact WLCSP, which is perfect for space-constrained applications.

In summary, the 24C04WQ from STMicroelectronics is a robust, efficient, and reliable EEPROM solution that offers excellent data storage capabilities for a wide range of applications, from consumer electronics to industrial control systems.
